Description

Can assemble superimposed PCCP pipe Technical Field The utility model relates to the technical field of PCCP pipes, in particular to a PCCP pipe capable of being assembled and overlapped. Background The PCCP pipe is a prestressed concrete steel pipe for short, and is a pipeline for conveying water, gas and other liquids. The steel cylinder consists of three parts, namely an outer layer of the steel cylinder, prestressed concrete and a lining steel pipe, and has high compressive strength and corrosion resistance. The existing PCCP pipe mainly comprises a concrete inner layer, a lining steel cylinder arranged on the outer side of the concrete inner layer, a concrete outer layer arranged on the outer side of the lining steel cylinder, a spiral groove reserved at one end of the lining steel cylinder and a spiral ring reserved at the other end of the lining steel cylinder, when two adjacent PCCP pipes are assembled and overlapped, the two PCCP pipes are mainly connected in a mode of enabling the two PCCP pipes to relatively rotate, and due to the fact that the PCCP pipes are heavy in structure, the assembly and overlapping efficiency between the two adjacent PCCP pipes is low due to the fact that the mode of relatively oppositely screwing is adopted, and efficient assembly and overlapping use of the PCCP pipes are inconvenient.
